The SR-3 is a compact bench top test chamber for use in evaluation testing of gas sensors using test gases of various concentrations without an additional gas supply control system. The intended concentration of test gas can easily be prepared in the chamber using the volume method. Injected gas is mixed with air by the built-in fan to achieve uniform gas concentration throughout the chamber.
In combination with the optional SR-D1A test unit, 8-series and 26-series Figaro gas sensors as well as pre-calibrated sensor modules can be quickly tested without users being required to develop driving electronics for each gas sensor. This test chamber is also compatible with Figaro’s other sensor evaluation modules such as EM5042 and EM8100.
